<h3>QTopo - Calibration data table</h3>
<p>
<br>
<p>

The calibration data are shown in a table with five columns:
<ol>
<li>the index of the group of the data. A group of calibration data
contains all the data taken in the same direction, rotating
the DistoX around the laser beam.</li>
<li>the "uncalibrated azimuth" of the data, ie, the azimuth computed
without the correction of the calibration.</li>
<li>the "uncalibrated clino" of the data, ie, the inclination computed
without the correction of the calibration.</li>
<li>the calibration error. For downloaded data this is zero before 
computing the calibration.</li>
<li>a flag to mark data that must be ignored when the caliration is computed.
This is used to leave spurious data, or bad data, out of the computation.</li>
</ol>
<p>
To sort the data by decreasing error double
click on the header of the <i>Error</i> column. To go back to the data 
arranged by the
group double click on the header of the <i>Set</i> column.
